Overall Impression

NOA Magazine is the monthly publication of the Japanese Origami Association. The complexity of the designs in the magazine tends to lean towards the more simple variety, but an occasional complex design is thrown into the mix.

The issues are usually centered around a theme, whether a holiday or season of the year. Most importantly, they are beautiful, with inspiring color-spreads and very high-quality diagrams.
